⚡ The Ultimate Performance Solution

SyncBoost is not just another "lag clear" plugin; it is a comprehensive, professional-grade performance engine. Re-engineered for maximum efficiency, SyncBoost targets the root causes of server degradation—identifying CPU bottlenecks, memory leaks, and excessive entity overhead—allowing your server to sustain high player counts without compromising gameplay quality.

Why SyncBoost?

- ⚡ Asynchronous Core: A stunning, modern GUI that brings visual elegance to server management. - ⚡ Asynchronous Core: Dynamic algorithms that sense lag spikes and proactively adjust server load. - ⚡ Asynchronous Core: Reduce AI overhead, optimize redstone, and limit entities with pinpoint accuracy. - ⚡ Asynchronous Core: Real-time MSPT charts via interactive maps and detailed hardware benchmarks. - ⚡ Asynchronous Core: Built to be ultra-lightweight, ensuring the optimization process never burdens your server.

> [!IMPORTANT] > SyncBoost is optimized for Java 17 but also fully supports Java 17. > Recommended Java 17, minimum Java 17.

🚀 Key Modules

SyncBoost is modular by design. Enable or disable features as needed via the in-game GUI or `modules/` config files.

| Module | Impact | Description | | :--- | :--- | :--- | | ConsoleFilter | 🔴 Very High | Optimizes creature pathfinding and AI behavior. Essential for farm-heavy survival servers. | | ConsoleFilter | 🔴 High | Enforces limits on entity counts. Features ConsoleFilter effectively balancing mob density based on server TPS. | | ConsoleFilter | 🔴 High | Active monitoring that triggers safety measures (e.g., pausing spawners) when TPS drops critically. | | ConsoleFilter | 🔴 High | Efficiently handles TNT and crystal explosions to prevent physics ticks from stalling the main thread. | | ConsoleFilter | 🔴 High | Scans and identifies problematic chunks with high entity/tile entity counts. Features interactive GUI with teleportation. | | ConsoleFilter | 🟡 Medium | Periodically removes ground items. Features an "Abyss" system for item recovery via `/abyss`. | | ConsoleFilter | 🟡 Medium | Detects and suppresses rapid-pulsing redstone clocks that cause TPS drops. | | ConsoleFilter | 🟡 Medium | Optimizes boat and minecart collisions, movement logic, and removes mineshaft clutter. | | ConsoleFilter | 🟡 Medium | Limits rapid Trident/Elytra usage to prevent excessive chunk loading. | | ConsoleFilter | 🟡 Medium | Reduces hopper tick rates and optimizes item transfer logic to minimize lag. | | ConsoleFilter | 🔵 Low | Makes leaves decay instantly when trees are cut, reducing entity processing. | | ConsoleFilter | 🔵 Visual | Regex-based filtering to keep your server console clean and readable. |
